Try out the app “Treble Cat” on your device’s App Store! It is a fun way to learn the notes on the treble clef.
I was introduced to this sight reading app by a family member, and I think those of us who teach kids (or want to learn as adults) may find it an effective tool to excite students about note identification and help students ascertain this skill.
There are also bass clef and rhythm versions, too!
